Owner-specified presumed pedigree, recorded as requested. Sigona's general consumer account describes Indio mandarinquat as a mandarin–kumquat cross but does not identify the exact parents or proportions. UCR's CRC 3759 account describes an open-pollinated Nagami seedling with pollen parent unknown, so the mandarin parent in this tree remains presumed and conflicts with that accession report; this is not verified parentage.
